Abstract
The interaction of Ce with Si (100) surfaces has been studied qualitatively by photoemission with synchrotron radiation. For coverages of a few monolayers the reaction yields a disordered phase with a wide variation of Si-Ce coordinations which do not depend on the distance from the surface. For coverages above 5 monolayers a mixed phase of Ce and a Ce silicide is found. Segregation of a Si-like phase to the surface does not take place.Keywords
